Changes to Source IPs for the Market Data Platform B Feed for Non-GLink Connections
Effective Sunday, June 17, 2012, CME Group will be changing multicast source IPs for the B feed only for non-  GLink connections. If a firewall or network device is configured with the source IP information, please correct your configuration to use the entire range of eligible addresses. Port, multicast addresses, and source IPs for each Market Data Platform channel are available in the config.xml file on the  FTP site as outlined in the Core Functionality of the  FIX/FAST SDK.

Market data will be broadcast on all CME Group FIX/FAST channels in the production environment for customer testing on Saturday, June 16. Market data will be broadcast from the new B feed source IPs.

• 8:30 - 9:00 a.m. CT: Connectivity testing
• 9:00 - 10:00 a.m. CT: FIX/FAST market data replay

As a reminder, CME Group requires that customers configure servers to connect to the Market Data Platform ports and multicast addresses for each desired channel. CME Group does not recommend restricting data flow via the source IPs, as these may change without notice.

If you have any questions or concerns, please contact your  Global Account Manager. If you experience any connectivity issues, please contact the CME Globex Control Center directly at 312.456.2391.
